Brunette Girl Undresses Her White Top And Blue Jeans At The Window

In the 1970's the denim and textiles industry introduced the stone-washing technique developed by GWG (Great Western Garment Co.). Donald Freeland Edmonton, Alberta pioneered the method, which helped to bring denim to a larger and more versatile market. Acceptance jeans continued through the 1980's and 1990's to the point where jeans are now a wardrobe staple, with the average North American owning seven pairs.
Dyeing
Traditionally, jeans are dyed to a blue color using indigo dye. Some colors that can be achieved however are pink, blue, yellow, black, and white. These colors are achieved by coloring other fabrics to resemble jeans. Approximately 20 million tons indigo are produced annually for this purpose, though only a few grams the dye are required for each pair these trousers.
